You do the smart thing and just get the heck out of there. There's no way to help that guy anyways, and you don't want to stick around just so you can be one of those... things.
Speaking of those things, there's still the matter of your freakishly long tongue. As soon as you figure you're a safe distance from to poor bastard you left back there, you dive into some bushes to deal with it. Ugh, it's so LONG! You grab at it, pulling and yanking and screaming to get it out, but it just stays there, rooted in place. You try to hide it in your mouth, but it's just too long to fit. Can you at least talk with this thing?
"Tethting, non prbbt sreh!"
Yeah... that doesn't work so great. So now you're out in the middle of the night with a two-foot-long latex animal tongue, completely unable to explain what's going on or give warnings about those latex werewolves to anyone. Could this get any worse?
